![]() ![]() Bounce Example with low elasticity/amplitude and high gravity/decay settings Limits to the Bounce Bounce Example with high elasticity/amplitude and low gravity/decay settings Amplitude/Elasticity – Value ‘amp’Īmplitude/Elasticity you should think of like a rubber band or bungee cord, the harder you pull it the more it bounces back in the opposite direction.įrequency/Maximum Number of Bounces – Value ‘freq’Īs it says on the tin, freq will give a definitive limit to how many times the layer/object will bounce based on this value. ![]() These are ‘amp’ for amplitude/elasticity, ‘decay’ for decay/gravity and ‘freq’ for the frequency/maximum number of bounces. ![]() The above expression may seem daunting at first but you really don’t need to know exactly how the code works, you just need to know how to manipulate a few parameters within it. It will interpolate the velocity of movement on that layer’s property for you by using the data within this expression’s code. All you need is two keyframes and After Effects will do the rest. Using an expression to create bounce is a great time-saving workflow that produces incredible results (that’s working smarter, not harder). Credit where credit is due, to Dan Ebberts who came up with this incredible expression and shared it with the community. ![]()
